SIPHON HEAD AND NECK.

Specification of Letters Patent.

Patented Aug. 29, 1905.

in the art to which it appertains to make and use the same.

This invention relates to certain improvements in siphon heads andnecks; and it has for its objects to produce such a device which can bereadily attached to an ordinary siphonbottle used for dispensing aeratedwaters and which will possess the requisites of strength and durabilityand which will be especially simple in construction and eflicient inoperation.

In this invention I have made provision for the ready refilling of thebottle without the necessity of the employment of expensive mechanismsuch as is now generally employed for that purpose.

By the employment of this device it is possible to dispense thesoda-water directly from the bottle or through the head thereof directlyfrom a larger storing-reservoir.

I have also arranged the neck in such a manner as to enable it beingreadily interposed between any ordinarily-formed head and theusually-constructed bottle, thereby affording many advantages withoutthe expense of providing a head especially constructed.

I am enabled to accomplish the objects of my invention by the meansillustrated in the accompanying drawing, in which the figure is avertical central section of the complete devlce.

Referring now to the above view by numerals and letters, 1 representsthe top of an ordinarily-formed glass siphon-bottle, encircling the neckof which is set the ordinarilyconstructed two-part metal collar 2, theouter surface of which is screw-threaded .to engage withsimilarly-formed threads in the base 3 of the metal head. Held securelyup against the inner roof of the base 3 by means of the upper rim of theneck of the bottle and the interposed rubber washer 4 is thefunnel-shaped member 5, to which is secured the ordinary glasssiphon-tube 6.

Adapted to reciprocate in a vertical channel 7 and bearing at its lowerextremity a rubber valve-head 8 is the stem 9, the upper extremity ofwhich terminates in a head 10, in which is formed adouble-inclinedV-shaped groove 11. Engaging with this groove 11 and held in the neck 12of the siphon-head is the pin 13. This pin is prevented from becomingdisplaced by means of the screw-cap 14.

Now assuming that the handle 15 is positioned at right angles to thatshown it will be readily seen that as the handle is turned the head 10will likewise turn, and owing to the presence of the pin 13 the head 10and stem 9 will be forced downward, thereby opening the valve covered bythe head 8 and thereby allowing the contents of the bottle to flow fromthe curved spout B. The spring 16, which encircles the stem 9, causesthe valve to close as the handle 15 is released. It will be readily seenthat the normal position of the pin 13 is right at the vertex of thegroove 11 and, further, that the handle can be turned in eitherdirection when it is desired to open the valve.

On the opposite side of the base 3 from the spout B is the pipe 17,which leads to the interior of the member 5, but is isolated from spoutB by the valve 8. This pipe can be readily connected to any suitablemetal reservoir by means of a flexible pipe and connecting-valves.

From the description so far gone into it is manifest that the bottle canbe readily refilled through the pipe 17 by first closing the valvehead8.

In refilling ordinary siphon-bottles through the siphon-tube it is awell-known fact that the bottle cannot be completely filled, owing tothe presence of air which is compressed in the upper neck of the bottle.Now in order to give a vent for this compressed air or gas I haveprovided the perforated screwcap C, which engages with a nipple D,formed integral with the siphon-head. In conjunction with this screw-capC, I have provided a perforated ring E, which is interposed between thetop of the bottle and the rubber washer 4. On the opposite side of thehead 3 is formed a tube F, to which is connected an ordinarypressure-gage G. By means of this gage the pressure of the contents ofthe bottle may be readily observed.

I am aw are that various changes in the form and construction of theseveral parts of my invention can be made without departing from thespirit thereof, and I therefore reserve the right to make such changesand alterations as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim, and desire toobtain by Letters Patent, is

1. A device of the class described provided I with a siphon-tube and aspout, a valve interposed between said tube and said spout, a suitablehandle, a valve-head, said head being formed with a V-shaped inclinedgroove, and a stationary pin engaging said groove substantially for thepurpose set forth.

2. A device of the class described provided with a siphon-tube andspout, a Valve interposed between said tube and said spout, a

suitable handle, a valve-head, said head being formed with a V-shapedinclined groove, a

pipe leading to said tube, and a stationary pin DEWIS LANDAU.
